	/// </summary>
	public class TimeSaleInfoSearch
	{
		private string startTime;
		private string endTime;
		public TimeSaleInfoSearch(string startTime,string endTime)
		{
			this.startTime=startTime;
			this.endTime=endTime;
		}
		public DataSet Search()
		{
			DataSetDBConnect ds=new DataSetDBConnect("table");
			ds.StrSQL="select SaleNo,SaleTime,BookName,Quantity,CustomerType,CustomerID from Book,Sale where Book.BookNo=Sale.BookNo and SaleTime between '"+startTime+"' and '"+endTime+"'";
